Integrated pipeline wall panels are modeled through a unified design, pre-positioning the panel layout and virtual location of pipeline fittings; cutting pipeline fittings to the corresponding lengths based on design dimensions; arranging pipeline fittings according to their virtual locations; manufacturing finished wall panels, creating panel pipeline channels at the arranged pipeline fitting locations, advancing the standardization of prefabricated building components and product integration, enhancing the efficiency of on-site assembly for prefabricated buildings, improving the construction environment, and preventing damage to walls from rough excavation, reducing the likelihood of wall cracking.
